\subsection{Front-end text processor} \label{subsec:front-end}
Front-end text processor produces Linguistic representation from the input text. This component does the majority of the text pre-processing and then gives the Linguistic Representation of the text to the Statistical Model. The task of pre-processing varies based on what kind of Front-end it is. There can be two types of front-end.
\begin{enumerate}
\item Trained front-end. \item Minimal front-end.
\end{enumerate}
\subsubsection{Trained Front End}
By trained front end, we mean a front end text processor which is trained on a specific language using language specific rules, grammar etc, e.g: Front end text processors of Festival \cite{festival}, Mary Text to

It depends on what type of text we are trying to normalize. There is no one consistent algorithm to normalize texts. It varies from language to language. One example of text normalization can be processing of NSW or Non-Standard Words, such as- year, cardinal number, ordinal number, acronyms etc. \par For example: For example: Consider the Bangla sentence, \textbengali{"আমি পরীক্ষায় ৭ম হয়েছি।"} Here, \textbengali{"৭ম"} is an ordinal number which is supposed to be pronounced as \textbengali{"সপ্তম" }। During text normalization we can replace \textbengali{"৭ম"} with \textbengali{"সপ্তম" }. \item \textbf{POS Taggging}\\ POS tagging or Parts of Speech tagging is labeling the tokens as their Corresponding Parts of Speech. POS tagging is done keeping in consideration what parts of speech the token is in its sentence. POS tagging helps in deciding prosodic information as different parts of speech tend to be pronounced differently sometimes.
.
\item \textbf{Phoneme Detection}\\ Phoneme detection is creating the pronunciation model, which contains phoneme set, that the text must follow. The tokens are basically broken down into phonemes by looking up a dictionary or some rules. A vast knowledge of the language is required to create the phoneme set and the dictionary. \item \textbf{Phrase Break}\\ Finding the proper position to put the prosodic break is another important step in
You will see these features a lot during your research project, and it is important that you know the purpose of those text features.
SWBAT utilize a Frayer model to generate of Tier 3 government words from a text.
In “I Won’t Hire People with Poor Grammar. Here’s Why” Kyle Wiens explains that Kyle wants to hire a people who have great grammar and he gives a reason why he said that. He regards grammar as an important part. His company which is iFixit is one the biggest online repair manual, that’s why employees need a good grammar to make the best manual. Kyle thinks good grammar makes a sense of successful business. In addition, his company thinks reliability is made through good grammar especially on the internet. Of course, writing and reading are less important than those who create manuals in their office. However, the company practice grammar test for all employees such as sales managers, staffs. This is because distinguishing the even small part
The first skill is to recognize if the reader can detect and match the initial sounds in words. When the student can accomplish that task, next she progresses to the final sound then move on to the middle sounds in the word. The second skill is to have the reader segment and produce the initial sound then progress to the final then the middle sounds. The third skill is the blending of sounds in the words. Fourth, the reader segment the phonemes in words and gradually progresses to longer words. The last skill is to manipulate phonemes by adding, subtracting and substituting sounds (Moats, 2009). When a student can accomplish these skills effortlessly than I would consider that reader to have strong phoneme awareness
Which is a also a very good site to use. It doses what the two does. It does the grammar, spelling check, writing suggestion, plagiarism detection. It
These simple programs check what you've written and then count the amount of times a certain word appears, using a Bayesan algorithm that assigns a “weight” to each word and then compares the weight of the different categories – such as weak male, strong female, etc. - and then assigns a percentage-based result to your
Although NegExpander works very good for this document, identifying all noun phrase , its total precision in identifying concepts correctly is only 93 percent.Finding some errors for incorrect part-of-speech tagging by Jtag, and some errors were made by NegExpander itself.
Full phoneme segmentation: Counting out the number of syllables. Speech practice with CVC words. Have students participate in silent reading and use their own ability to sound out words they don’t know with syllable practice. Students can count the number of syllables in a rhyme or poem, they can clap together counting syllables in
Using grammar, differentiating words like ‘to’ and ‘two’ or ‘right’ and ‘write’ is possible. Grammar is also used to speed up a speech recognition system by narrowing the range of the search (6,p.98). Grammar also increases the performance of a speech recognition system by eliminating inappropriate word sequencing. However, grammar doesn’t allow random dictation which is a problem for some applications (6, p.98).
By utilizing the millions of misspelled words in the billions of searches it processes every day, Google was able to create it’s spell checker for free (something that Microsoft spent a considerable amount of time and money to create). Google then created an ingenious way to confirm that it’s algorithm displayed the correct word by asking users to click to confirm on the corrected search results. In addition, google took their algorithm a step further by looking at the text of the web pages that they click on as the page that the user selects as the page likely has the word spelled correctly if the user selected it. This allows google to continually improve their spell check and also makes it easily available for any language that is typed into their search engine. This data also has additional uses beyond spell check, such as their “autocomplete” feature that is available across most of the google ecosystem and the translation services that they offer9.
Speech recognition (also known as automatic speech recognition or computer speech recognition) converts spoken words to text. The term "voice recognition" is sometimes used to refer to recognition systems that must be trained to a particular speaker—as is the case for most desktop recognition software. Recognizing the speaker can simplify the task of translating speech.
Preprocessing is actually a trail to improve text classification by removing worthiness information. In our work document preprocessing involve removing punctuation marks, numbers, words written in another language, normalize the documents by (replace the letter ("أ إ آ ") with (ا""), replace the letter (ء ؤ" ") with (""ا), and replace the letter("ى") with (""ا). Finally removing the stop words, which are words that can be found in any text like prepositions and pronouns. The rest of words are returned and are referred to as keywords or features. The number of these features is usually large for large documents and therefore some filtering can be applied to these features to reduce their number and remove redundant features.
Tokenization is the process of dividing the document into smaller pieces of word that is called token. The splitting up into tokens can be done with decision trees, which contains information to correctly solve the questions you might encounter. Some of these issues you would have to consider are:
Next, experiment results confirm that there is a decrease in the accuracy when training and testing phases use different domain corpora. For example, in the individual SVM based tagger, the best accuracy of 88.24% is achieved when the training and testing is done using a combination of both Official Documents and News (E3). But when the tagger is trained with news and tested with official documents (E5), the accuracy is 82.01%, which is a decrement of 6.23%.
